Question

5(x+3)(x+2)-3(x2+2x+1)

Answer 1

[ Answer ]

$\boxed{5x^{2} \ + \ 13x \ + \ 27}$

[ Explanation ]

• Simplify: 5(x + 3)(x + 2) - 3(x2 + 2x + 1)

--------------------------------------

• Add Similar Elements: 2x + 2x = 4x

5(x + 3)(x + 2) - 3(4x + 1)

• Expand: 5(x + 3)(x + 2) - 3(4x + 1): $5x^{2}$ + 25x + 30

$5x^{2}$ + 25x + 30 - 3(4x + 1)

• Expand: - 3(4x + 1): -12x - 3

$5x^{2}$ + 25x + 30 - 12x - 3

• Simplify: $5x^{2}$ + 25x + 30 - 12x - 3: $5x^{2}$ + 13x + 27

= $5x^{2}$ + 13x + 27

$\boxed{[] \ Eclipsed \ []}$
